One of the most common mistakes that students make when writing their college essays is not taking the time to proofread and edit their work. This can lead to grammar and spelling mistakes that can make the essay difficult to read and understand. Additionally, students often fail to make sure that their essay is structured in a logical and organized manner. This can lead to a disjointed essay that does not flow well and does not make a strong argument. Finally, many students fail to properly cite their sources when using quotes or research from outside sources. This can lead to plagiarism, which can lead to serious consequences.
